Operating over a single pin, the built-in challenge-and-response SHA-1 authentication scheme in the DS28E01-100 prevents unauthorised product builds and safeguards FPGA IP. The reference design allows manufacturers to remotely turn on fee-based software-controlled feature upgrades, without physically altering the installed hardware. The security scheme requires secret keys to be loaded in the FPGA and the 1-Wire secure memory. Maxim’s reference core seamlessly overlays on the Spartan-6 device; utilizes less than 5% of the logic cell resources and eases the loading of secret keys into the FPGA. Maxim can also preprogram the DS28E01-100 with customer-specified keys prior to delivery.
“Maxim’s security system provides best-in-class protection for licensing control and feature-set upgrades. If the DS28E01-100 and the FPGA do not ‘recognize’ each other, the FPGA design is effectively disabled,” said Prem Nayar, Business Manager for Secure Information & Authentication Products at Maxim Integrated Products.
In 2010, the Brand Protection Alliance reported that the World Customs Organization and Interpol estimated the global trade in counterfeit goods has increased from US$5.5 billion in 1982 to approximately US$512 billion annually. Approximately 5-7% of world trade is in counterfeit goods.
